Qwen-3-Serie
Qwen3 definiert offene LLMs mit dynamischen Thinking-Modi neu und glänzt bei Code, Mathematik und mehrsprachigem Reasoning. Angetrieben von sparsamen 22B aktiven Parametern, vereint es rasante Geschwindigkeit mit tiefer Intelligenz – vollständig Open Source, von leichtgewichtig bis hin zu 235B-Giganten. 1. Grundlegende Verwendung: Forwarding im OpenAI-kompatiblen Format.2. Tool-Aufrufe: Reguläre Tools unterstützen das OpenAI-kompatible Format, während MCP-Tools auf qwen-agent angewiesen sind und vorab die Installation der Abhängigkeiten erfordern:
pip install -U qwen-agent mcp.

Qwen 2.5 und QwQ/QvQ-Serie
Verwenden Sie das OpenAI-kompatible Format zum Forwarden. Der Unterschied: Beim Streaming-Aufruf müssen Siechunk.choices[0].delta.content extrahieren, siehe unten.
1. QvQ, Qwen 2.5 VL: Bilderkennung.2. QwQ: Text-Aufgabe.
